SHOW-CASE LIGHT.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed December 21, 1912. Serial No. 737,955.

To-all whom it may concern Be it known that I, ALFRED l/VILLIAM BEU'r'rELL, a subject of the King of Great Britain, residing at Streatham, London, England, electrical engineer, have invented certain new and useful Improvements in Show-Case Lights, of which the following is a specification.

This invention relates to appliances or means for mounting incandescent electric lamps and to the manufacture thereof and more particularly to appliances or means for mounting incandescent electric lamps of the type known as tubular or double ended tubular electric lamps or so-called straight filament lamps.

- The inventionwill be more particularly pointediout andfully described in the following portion of this specification and in the'clai'm's thereof, and as showing certain specific embodiments of theinvention reference 'is made to the drawings forming a part :of this specification and in which drawings-Figure"1 isa plan view of an illuminating appliance according to the present invention. Fig. 2 is a section view thereof on the line 22 showing a separate detachable reflector mounted in the concavity of the reflector body. Fig. 3 is a sectional view 1 of the modification showing the concave side ';Of the reflector body finished as a reflecting "surface and showing also a spring clip adapted for mounting the illuminating appliance in position. Fig. 4 is a sectional viewof a further modification, showing the exterior or concave side of the reflector body coated'with a metallic covering. Fig. 5 is asectional view of a further modification showing the appliance provided with a corrugated glass screen. Fig. 6 is a sectiona view of another modification showing the whole of the device coated (inside and outside) -with a metallic covering and provided with a glass screen, and showing a spring clip adapted to hold said screen in position. Figs.'7, 8 and 9 aresectional views of that portion of the reflector body immediately surrounding the channel orconduit for the conductor wires illustrating various modifications of the same. Fig. 10 is a sectional view of a modification showing an open channel located on the convex side of the reflector body, which is, however provided with aseparate detachable reflector on the concave side thereof. I

"i fReferringnow particularly to Figsil and 2, A is a reflector body being a continuous moulding of wood or other suitable material capable of being made in long lengths. B is a separate detachable reflect-or mounted in the concave side of the reflector body A, which concave side of the reflector body A is here shown to conform only approximately to the cross-section of the reflector B. By this means it is possible tosomewhat vary the precise shape of the reflector B without necessarily changing the interior cross-section of the reflector body A. The reflector body A is provided on each side edge thereof with internally projecting edges or beads C for the purpose of receiving and holding the edges of the separate reflector B in position with the reflector body' A. At the bottom of the reflector body A is provided a channel or conduit D formed in the substance of the reflector body on the concave .side, thereof for the purpose of-receiving the conductor wires therein. The channel or conduit D is open along one-side (the upper side) thereof and this open side is covered over with the separate reflector B when mounted in position in the reflector bodyA.

Mounted in the appliance is shown the lamp socket or lamp holder E carrying one end of each of two double ended straight filament or tubular lamps F. The grooves G- G are provided on the convex side of the reflector body A for receiving or engaging any suitable spring clips as described.

Referring now particularly to Fig. 3, the f reflector body A is formed onthe concave side thereof as a reflecting surface of metal,

porcelain, enamel or any other suitable reflecting material, or as previously described by preparing the concave surface shown by the thick line B and electro-depositing thereon a coating of suitable reflecting material. In this instance thechannel I) for the conductor wires is shown located at a dis tance beneath the concave surfm-e of the reflector body A. The hinged spring clip H is shown provided with a spring memberJ,

carrying on its outer ends members K K engaging the longitudinal grooves G G of the reflector body A.

Referring particularly to Fig. 4 there is here shown a modification where the convex side of the reflector hodyA is coated with a metallic covering shown by the thick line-L by the process such as hereinbefore' described of electro-depositing the same thereon or in any other suitable manner. In this instance a separate reflector B is shown as in Fig. 2 and is made to conform exactly with the shape in cross-section of the concave side of the reflector body A and said separate reflector covers over the open side of the channel or conduit D.

Referring now to Fig. 5, the longitudinal grooves or recesses M are formedin the substance of the reflector body A near to the top inside edges thereof to receive the transparent (corrugated or otherwise) screen N therein, which is adapted to he slid along said grooves from one end of the appliance to the other.

Referring now to Fig. 6 the reflector body A is here shown enveloped completely by a metallic casing 0 (shown by the thick line) electro-deposited thereon as described or applied thereon in any suitable manner, the concave side of said metallic envelop serving to act as a reflecting surface; or the reflector body A may be treated or painted in any suitable manner to form a reflecting surface on the interior thereof and a suitable finish on the exterior thereof, both-of which surfaces will be represented by the line O-O. In this instance the transparent. screen N rests .in the recesses P P formed in the inside upper edges of the reflector body A and is held in position by spring clips shown by the thick line Q engaging at their outer extremities R R the longitudinal groove G G in the reflector A, or the transparent screen N may be otherwise mounted in such reflector body as for example in the manner shown in Fi 5-.

Ref erring now to Fig. 7, the channel or conduit D is formed on that side, of the reflector body A farthest removed from the reflector B, is open at one sidethereof and is adapted to be covered over by the strip or plate S which is attached any-suitable manner to the reflector body A.

Referring now to Fig. 8, there is here shown a modification of the last described arrangement where the channel or conduit D is closed by inserting the separate inverted detachable cover T of U shape into the channel or conduit D.

Referring now to Fig. 9, there is here shown a further modification in which the channel or conduit D is covered over by a thin metal or other plate OlfStI'iP U screwed on to the reflector body A. Referring now to Fig. 10, this figure serves to illustrate a modification-of the deviceshown in Fig. 2 where the channel or conduit D is formed on the convex side of the. reflector body A instead of on. the concave side thereof. The channel-or conduit D may be covered over iii-desired by any ofthe methods shown in Figs-7, 8 and 9 or in anyother, suitable manner.-

The improvements herein set forth are. not

to the precise construction and ar- :being provided. with. longitudinally extendrangement "shown and" described, as they may be embodied in various forms and modifications without departing from the spirit andscope of the invention.
